| Abstract | ||
| Water harvesting and increasing moisture project are implemented for various tarrgets. In arid areas that water shortage is the major limitation factor for vegetation cover development, every work for increasing moisture and precipitation storage can be the cause of vegetation cover improvement. In this research the effects of crescent like-micro cachment as one of these project on functional characteristics of vegetation cover specially on key species 11years was investigated. For this purpose in each portion by means of control and implementig site as representatives of treatments was identified. In every ereas 14 transect with 400meters longs and on each transect 2 plot 8 m2 was established. After record of species list that had presented into the frame, characteristics such as canoy percent, number, plant size and litter was recorded separately. Compreffion by use of independent t-test was taken place respectively. Results showed canopy Implementing piece from 11/9 to 20.56 percent, production from 3.18 to 5.23 gr/m2 litter from 0.8 to 1.29 gr/m2 have reached. Also results showed increasing canopy, density, volume of stand live mels of Artemisia santolina species and decrease invasion species, Hammada salicornica difference total canopy, key species canopy, dry matter production and litter in 0.05 was significant due to implementing of this project. In other side variations of density and volume of stand live mass of this species showd significant difference in %1 respectively. In plant composition the portion of key species has been increased and protion of invesion species has been decreased respectively. | ||
